Site details

Kismet Reef is a small 10-acre NYSDEC artificial reef in Great South Bay, just north of the South Beach between Kismet and the National Seashore dock, in 16-25 ft of water. Built from barges, concrete barriers, blocks, slabs, culvert and rubble, it is a sheltered, shallow bay reef good for newer divers. Visibility is limited and tide-dependent; black sea bass, tautog, scup and flounder use the structure.
